HARROW AND CULTIVATO R.

SPECIFICATION forming part of Letters Patent No. 358,321, dated February 22. 1887.

(No model.)

To all whom it may concern:

Be it known that I, JAMEs GAGE BAILEY, of the village of Richmond Hill, inthe county of York, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Harrows and Cultivators, of which the following is a specification.

The object of the invention is, first, to design a light metal frame possessing the necessary rigidity to render it serviceable as a cultivator or harrow frame; secondly, to devise simple means for attaching the teeth to the said frame; land it consists, iirst, in providing a bar-metal frame, preferably of light steel, with angle or T shaped edges,being connected to the said frame by peculiarly-shaped blocks, together with bolts or keys, arranged substan tiall y as hereinafter described.

Figure l is a view of the harrow with my improved metal frame and teeth secured in position in accordance with my invention. Fig. 2is an enlarged perspective detail showing the manner of securing the teeth to the frame. Fig. 3 is a perspective detail ot a crossblock for connecting the bars of the frame together. Fig. 4 isa perspective detail of the three teeth of a cultivator attached in accordance with my invention to my improved metal frame. Fig. 5 is a crosssection of the frame Fig. 6 is a detail showing an alternative form of metal bar for frame. Fig. 7 is a detail of the tooth-saddle.

It will be noticed that the frame consists of light metal bars rolled with their edges raised above their center portion, preferably forming a double T-shaped bar; but instead of the' double T-shaped bar an angle-bar, as shown in Fig. 6, would, in a measure, answer the purpose of my invention.

Between the lips a, forming the edges of the T or angle shaped bars A, I insert a metal block, which, when used in connection with a harrow-frame, is formed like a double block, B, as shown in Fig. 3, and the block thus shaped like B is inserted between the lips a ou the frame A at the point where the bars cross each other, one portion of the block B fitting between the lips a on the bottom side side of the frame A. A bolt, C, passing through the saddle D, both bars of the frame A, and through the block B, secures them to.- gether, as shown.

Should the bars of the frame A be made the shape shown in Fig. 6, the block B, instead of Y iitting between the lips a and the frame A, would have lips b formed on the said block,to catch the crossing bars of the frame A, as indicated in Fig. 6.

When the tooth is to be applied to the frame A,I attach the saddle D at the point indicated in the drawings, and either carry the bolt O through ahole in the said saddle and through a hole in the tooth E, as shown in Fig. 7, or I simply bolt the saddle D in position and place the tooth E on the said saddle between the jaws d. I slip a key, F, through holes in the jaws d, as indicated in Fig. 2, and by tightening said key F,I rigidly secure the tooth E in the desired position. M

In Fig. 2 I show detachable wedge, G, which I use for the purpose of changing the angle of the tooth E. When the wedge G is placed in the position indicated in full lines in Fig. 2, the point of thetooth E is thrown down, and by placing it on the opposite side of the saddle D (indicated by dotted lines in Fig. 2) it is thrown up. y Instead of providing a detachable wedge, G, the bottom of the saddle D may be slanted or made Wedgeshaped, as indicated in Fig. 7. With this improvement it is merely necessary to reverse the saddle D when it is desired to alter the angle of the tooth. Vhen my inventio-n is to be applied to a cultivator,I change the shape of the saddle D from that shown in Figs. 2 and 7 to the styles shown in Figs. 4 and 5. In this latter style the saddle D is merely a bevel-block tted between the lips a and provided with lips e, to fit against each edge of the tooth E and prevent the said tooth, when placed in position, as indicated in Fig. 4, from twisting on its bolt C, which passes through the frame, block, and tooth. When a block of this description is employed, the angle of the tooth is altered by simply reversing the block, and consequently the angle of of the frame A, while the other portion of the 5o block B, which is set at right angles to its upper portion, :tits between the lips a on the top the said tooth E may be altered, as in the Ioo other form of construction, without iniroducing an oblong bolt-hole through the tooth.

5 B is not absolutely necessary, and may sometimes be omitted.

Vhat I claim as 1ny invention is- 1. A cultivator or harrow frame composed of light metal bars A, having lips a, formed 1o on their edges, in combination with blocks D,

fitted between the lips of said bars at their points of intersection, and bolts C, substantially as and for the purpose specified.

2. The frame or bar A, having lips a formed on its edges, in combination with the blocks B and a beveled block or saddle fitted between the lips a, and forming a seat for the tooth lf., which is secured by the bolt C, substantially as and for the purpose specified.

3. The frame or barA, having lips a formed on its edges, between which the block or saddle D is placed, in combination with the tooth E, fitting between the lips d, formed on the saddle D, and rneans for binding them t0- gether, substantially as and for the purpose specified.

4. The bar or frame A, havinglips aformed on its edges, in combination with the saddle D, having the bottoni shaped to fit between the said lips a, and the tooth E, fitted between the jaws d on the saddle D and rigidly secured by means of the key F, substantially as and for the purpose specified.

5. rlhe frame or bar A, having lips a formed on its edges, between which the bottom of the saddle D iits, in combination with the wedge G, either detachable or solid with the saddle, and Aforming a seat .for the tooth E, which is secured in position by the key F, substanlially as and l'or the purpose speciiied.
